Preparation of Examples 135-138

(236) To a mixture of intermediate 2 (1.0 eq), Cs.sub.2CO.sub.3 (1.0 eq) and NaI (0.05 eq) in DMSO (5-12 mL) a suitable, commercially available halide (0.75 or 1.0 eq) was added dropwise, and the reaction mixture was stirred at r.t. for 3 hrs. The reaction mixture was quenched by addition of NH.sub.4Cl and extracted with EtOAc. The organic layers were combined and concentrated under reduced pressure. The crude product was purified by HPLC giving the pure desired compound. (y=19%-39%)

(245) Purification System

(246) HPLC Preparative

(247) HPLC system WATERS Quaternary Gradient Mobile 2535 equipped with WATERS UV/Visible Detector 2489 set to a dual-wavelength UV detection. Two mobile phases were used, mobile phase A: water (MilliQ) 0.05% TFA; mobile phase B: acetonitrile (Chromasolv Sigma-Aldrich) 0.05% TFA, and the run gradient conditions were set specifically for each compound. The purifications were achieved on a LUNA C18 Phenomenex Column 5 μm 19×150. An injection volume between 100 and 500 μl was used and the flow was 15 ml/min.

(248) Racemate Separation

(249) The two enantiomers 148 and 149 were obtained by resolution of the racemic mixture 128 using a WATERS Quaternary Gradient Mobile 2535 equipped with WATERS UV/Visible Detector 2489 set to a dual-wavelength UV detection at 220 and 260 nm. The chiral resolution was achieved on the Kromasil 5-Amycoat column (250 mm×4.6 mm, particle size 5 μm) using N-Hexane (Chromasolv Sigma-Aldrich)—Ethanol (Chromasolv Sigma-Aldrich) 90-10 (v/v) as isocratic mobile phase; The sample was eluted from the column at a flow rate of 1.0 ml/min at room temperature (Pressure: ≈600 psi). The mixture was dissolved in Ethanol at concentration of 1% (w/v) and the injection volume was 15 μL.

(250) LCMS

(251) LCMS General Procedure

(252) The HPLC measurement was performed using a Dionex 3000 module comprising a quaternary pump with degasser, an autosampler, a column oven (set at 29° C.), a diode-array detector DAD and a column as specified in the respective methods below. Flow from the column was split to a MS spectrometer. The MS detector (LCQ Fleet Thermo Scientific) was configured with an electrospray ionization source. Mass spectra were acquired by scanning from 50 to 800 in 0.48 second. The capillary needle voltage was 5 kV in positive and negative ionization mode and the source temperature was maintained at 275° C. Nitrogen was used as the nebulizer gas, the flow was 8 l/min. Data acquisition was performed with Thermo Xcalibur Qual Browser.

(253) LCMS—Procedure

(254) In addition to the general procedure, reversed-phase HPLC was carried out on a Kinetex XB-C.sub.18 column Phenomenex (1.7 μm, 50×2.1 mm) with a flow rate of 0.300 ml/min. Two mobile phases were used, mobile phase A: ammonium formate buffer solution at pH 3.5; mobile phase B: acetonitrile (Chromasolv Sigma-Aldrich), and they were employed to run a gradient conditions from 15% B to 98% in 4.5 minutes, hold these condition for 1.35 minutes and then 15% B in 0.1 minutes and hold these conditions for 3 minutes in order to reequilibrate the column.

Pharmacological Examples

(259) Examples of the Invention were Found to be P2X7 Inhibitors Using a Screen Quest™ Fluo-8 No Wash Calcium Assay Kit.

(260) Extracellular binding of Bz-ATP to P2X7 receptor opens the channel and allows Ca2+ influx into the cells. This Ca2+ entry was measured in HEK-293 cells stably transfected with P2X7 receptor using Screen Quest™ Fluo-8 No Wash Calcium Assay Kit (AAt Bioquest®, cat. 36316). Once inside the cell, the lipophilic blocking groups of Fluo-8 are cleaved by non-specific cell esterases, resulting in a negatively-charged fluorescent dye that stays inside cells. Its fluorescence increases upon binding to calcium. When HEK-293/P2X7 cell are stimulated with Bz-ATP, Ca.sup.2+ enters the cells and the fluorescence of Fluo-8 NW increases. The dye has an absorption spectrum compatible with excitation at 488 nm by argon laser sources and its emission wavelength is in the range of 515-575 nm.

(261) HEK-293 cells stably transfected with P2X7 receptor were seeded overnight in growth medium at 10,000 to 20,000 cell/well in 384-well plate. 24 hours later, the medium was removed and the cells were pre-loaded at RT for 1 hour with 20 μL/w of Fluo-8 NW. Then 10 μL/w of tests compounds and reference antagonist A438079 at 3×-concentration were injected with the FLIPR.sub.TETRA and the kinetic response over a period of five minutes was monitored. A second injection of 15 μL/w of 3× reference activator (Bz-ATP at EC.sub.80) was performed with the FLIPR.sub.TETRA and the signal of the emitted fluorescence was recorded for additional three minutes. All the experiment was carried out in a Low Divalent Cation Assay Buffer (0.3 mM Ca.sup.2+ and 0 mM Mg.sup.2+). The effect of the test compounds was measured as percent inhibition vs the reference antagonist and IC50 values were calculated accordingly. Here are reported the potency ranges as A, B, C and D, where A is <200 nM; B is 200 nM-104, C is 1-10 μM, D is >10 μM.

(263) Examples of the Invention were Found to be P2X7 Inhibitors Using YO-PRO®-1 Uptake Assay.

(264) YO-PRO®-1 is a fluorescent DNA-binding dye with a MW of 374 Da (Molecular Probes®, cat. Y3603). This method is based upon the presumed ability of YO-PRO®-1 to enter through the dilated or “large pore form” of P2X7 receptor and to bind to intracellular DNA whereupon it increases many fold its fluorescence intensity. The dye ha an absorption spectrum compatible with excitation at 488 nm by argon laser sources and its emission wavelength is in the range of 515-575 nm. The aim of this assay was to validate the interaction of antagonists with P2X7 receptor using an alternative readout to Ca2+-sensitive fluorescent dyes.

(265) HEK-293 cells stably transfected with P2X7 receptor were seeded overnight un growth medium at 20,000 cell/well in 384-well plate. 24 hours later, the medium was removed, the cells were washed with Low Divalent Cation Assay Buffer (0.3 mM Ca.sup.2+ and 0 mM Mg.sup.2+) and then pre-loaded with 20 μL/w of 5 μM YO-PRO®-1 dye.

(266) FLIPR.sub.TETRA fluorescence measurement immediately started. Then 10 μL/w of test compounds and reference antagonist A438079 at 3×-concentration were injected with the FLIPR.sub.TETRA and the kinetic response over a period of five minutes was monitored. A second injection of 10 μL/w of 3× Bz-ATP EC.sub.80 (30 μM) was performed with the FLIPR.sub.TETRA and the signal of the emitted fluorescence was recorded for additional 60 minutes. All the experiment was carried out with a Low Divalent Cation Assay Buffer (0.3 mM Ca.sup.2+ and 0 mM Mg.sup.2+).

(267) The effect of the test compounds was measured as percent inhibition vs the reference antagonist and IC.sub.50 values were calculated accordingly.

(269) Examples of the Invention were Found to be Active on Human P2X7 Channel Assay by Automated Patch-Clamp.

(270) In order to directly monitor the block of P2X7 channel, an electrophysiological assay was developed and implemented on the QPatch16X automated electrophysiology instrument.

(271) HEK-293 cells expressing the P2X7 channels were cultured in modified EMEM.

(272) 72 hours before experiment, 5 million cells were seeded onto T225 flasks. Just before the experiment cells were washed twice, detached from the flask with trypsin-EDTA, re-suspended in the suspension solution and placed on the QPatch 16x.

(273) The compounds (20 mM in a 100% DMSO) stored at −20° C. were prepared the day of the experiment (a first dilution 1:20 in 100% DMSO to prepare a 1 mM stock solution, then a 1 microM solution in external solution+a serial dilution 1:10).

(274) The standard whole-cell voltage clamp experiments were performed at room temperature. From these experiments the multihole technology was used and the data were sampled at 2 KHz.

(275) The intracellular solution contained (mM) 135 CsF, 10 NaCl, 1 EGTA, 10 HEPES, (pH 7.2 with CsOH) whereas the extracellular contained (mM) 145 NaCl, 4 KCl, 0.5 MgCl.sub.2, 1 CaCl.sub.2, 10 HEPES, 10 Glc (pH 7.4 with NaOH).

(276) After establishment of the seal and the passage in the whole cell configuration, the cells were held at −80 mV. The P2XR7 current was evoked by applying 100 microM of BzATP alone (4 times) and then in the presence increasing concentrations of the compound under investigation (1, 10, 100 and 1000 nM).

(277) The pre-incubation periods 5 to 8 contain increasing concentrations of the compound of interest (1, 10, 100 and 1000 nM), as illustrated in FIGURE (application protocol).

FIGURE: APPLICATION PROTOCOL

(278) The maximal inward current evoked by BzATP in absence or presence of increasing concentrations of the compounds under investigation was measured and normalized. The potential agonist effect was measured as % of control and as IC50 determined fitting the dose-response curves data with the following equation:
Y=100/(1+10{circumflex over ( )}((Log IC50−X)*HillSlope))

(279) Where:

(280) X=log of concentration

(281) Y=normalized response, 100% down to 0%, decreasing as X increases.

(282) Log IC.sub.50: same log units as X

(283) HillSlope: slope factor or HS, untiless.
